Measurable time of all-pulse measurement for each mode:
CYC-AC 5,000 ms max. (50 Hz: 250 CYC, 60 Hz: 300 CYC)
ms-DC 2,000 ms max.
CYC***Hz-AC 4,000 ms max. (M050 (50 Hz): 200 CYC, M063 (63
Hz), 250 CYC, ... M500 (500 Hz): 2,000 CYC)
CYC-DC 2,000 ms max. (50 Hz: 100 CYC, 60 Hz: 120 CYC)
ms-AC 5,000 ms max.
SHORT ms-DC 300 ms max.
LONG CYC-AC 10 s max. (50 Hz: 500 CYC, 60 Hz: 600 CYC)
No impulse measurement is performed. Select SET
PULSE for PULSE MODE, and “00” for PULSE No.
• SET PULSE
Used when performing the 1-step welding (current is not passed several
times) in a single welding sequence or when performing the multi-step
welding in a single welding sequence and measuring the specified step
1) 1-step welding (current is not passed several times) in a single welding
sequence
Set PULSE No. to “00” (no impulse measurement is performed).
a: WELD
The next measurement is made after a measurement ends.
(Note) For measurable time, refer to “Measurable time of all-pulse
measurement for each mode.”
2) When performing the multi-step welding in a single welding sequence and
measuring the specified step
Set an arbitrary step number to measure to PULSE No.
01: Measures the first step, 02: Measures the second step,… 20: Measures
the twentieth
step
When the interval of the several current flows is less than 500 ms, a
measurement is made as a single sequence. When 500 ms elapses, a
measurement is made as another sequence.
